Mount Sinai girls lacrosse kicked off its game about an hour late after a track meet tied up the field, but don't tell Sydney Pirreca that. For her, the race never ended. Pirreca, a physical midfielder headed to Florida (eventually . . . she's a sophomore), translated her whiplash speed to head-turning results Wednesday, scoring five goals en route to a 10-6 win over Harborfields in Suffolk Division...

"She's got this just explosive speed," coach Al Bertolone said. "Every time she has the ball, she's a threat to go . . . you really can't prepare for that kind of speed."

Harborfields had plenty of trouble catching up, as Pirreca scored the first two goals of the game -- on a blazing drive to the cage, punctuated by an overhand blast, and the other on a quick flip on a feed from Caroline Fitzgerald. The Mustangs led 8-2 at the break, thanks to Pirreca's man-up streak from about 30 yards.

"It was 100 percent my advantage," Pirreca said. "It's easier to run past them. That's what I use most, that' my biggest skill and that's what I use as much as I can."

When Harborfields did threaten they were met by Julia Michaels, who made eight saves. Her best work came in that early onslaught, when the junior made a stop on a free-position attempt five minutes in, a stick save off a point-blank shot with 17:43 left in the first half, and another save off a free position a minute later.

Katie White had three goals and Carli Clementi scored twice for Harborfields. Danielle DellaRocca and Kasey Mitchell had two goals for the Mustangs.

"It was a little rough," Michaels said. "All you can really see is the silhouette of the girls, so as the goalie, all I'm really looking at is the top of your stick and whatever that ends up . . . And my defense saved my butt for everything. It was insane."

Michaels added that the matchup had historically been a difficult one -- Harborfields beat them by one two years ago, and the Mustangs pulled out the one-goal win last year.

"We've been battling them game for game, goal for goal," she said. "So for us to come out on all six cylinders shows that we're Mount Sinai, and we can pull it together as a team."
